CIGA Design TOURBILLONvsMarathon Steel Navigator SSNAV Auto

The CIGA Design TOURBILLON is praised for its avant-garde design, well-finished titanium case, and the spectacle of its in-house tourbillon movement, offering a unique entry into this complication at a relatively accessible price point. Owners and reviewers highlight the visual engagement provided by flame-blued titanium parts and guilloche casebacks, with some noting the wearability of the 45mm titanium case due to its 11.65mm thickness and updated strap design. However, movement performance is a point of contention, with one owner reporting degraded accuracy as the power reserve depletes and a lack of tactile feedback during winding, hacking, or a power reserve indicator. Readability can be challenging due to dark dials and hands that can be difficult to see, and water resistance is limited to 30 meters.

The Marathon Steel Navigator SSNAV Auto is praised for its high-accuracy quartz movement, with owners noting its comfort and reliable performance. Reviewers highlight its functional tool-watch appeal, featuring a sandblasted steel case, tritium tubes for constant low-light visibility, and 100-meter water resistance. One owner finds the 41mm case runs a bit small. The Marathon Steel Navigator SSNAV Auto utilizes an ETA F06.412 quartz movement with a claimed accuracy of +/- 10 seconds per year and includes a GMT bidirectional bezel. Overall, owners and reviewers rate the Marathon Steel Navigator SSNAV Auto highly for its comfortable wear and dependable, high-accuracy quartz movement.
